i.mx6 Android line-out audio max volume is very low and not really loud

I have tested audio with various i.mx6 boards with Android: Wandboard Solo, Wandboard Quad, RIoTBoard and Sabre Lite


By all of them I enabled the line-out jacks and disabled all other sound devices in the Android kernel_imx.

In the Android settings I switch the volume to the very maximum. But on all boards the max sound is not really loud. Comparable to usual taking.


I expected a much higher volume since I was thinking that line out has always the same max signal level. If I try the same speakers with PC line-out it is much louder.


Is there any way to increase the max volume in Android for the sgtl5000 codec? As said I have access to the Android source so any possible patch would be appreciated,


Many Thanks
